the Sierra Nevada in the south and the Rocky Mountains in the north; the highest peak is Mt. Whitney (4,540 m) in the Sierra Nevada. The Cordilleras are still an active region of the Earth. There are a number of active volcanoes there and often earthquakes shake the land. Hot springs and geysers are numerous in Yellowstone. Between the mountains there are many canyons. The most famous of them is probably the Grand Canyon. The highest peak in America is Mt. McKinley with its 6194m. The lowest point is the Death Valley - 86m. Between the mountains are the central lowlands called the prairie and eastern lowlands called the Mississippi valley. One of the most famous mountains in the USA is Mount Rushmore in South Dakota because of the faces of presidents Washington, Jefferson, Lincoln and Roosevelt that have been cut in the rock.
